RE: WBMM> Queues






I can certainly think of "remote" service cases where set and queue 
management would be appropriate.  IMHO, we should not fundamentally 
declare in the spec what can and cannot be done over a firewall or across 
a domain: this is exactly what our authentication scheme should do.  Many 
customers may not allow set or queue management externally, but many will.
 
As for whether NetSilicon should implement set and/or queue management for 
proxy solutions, if they are "required" for whatever profile of WBMM you 
are supporting, you should implement them - but if you are sure that your 
customers will never allow you to expose them to an external client, you 
could make them stub implementations that always returned "not 
authorized".  This would allow you to deliver the solution your customers 
want without unnecessarily binding other WBMM use cases.

Harry,
 
One of the most immediate  applications of WBMM,  for which no standard 
capability  now  exists, is in remote monitoring. In general, any set 
operation (and many get operations)  must be disallowed for enterprise 
security and confidentiality purposes. If one is producing proxy devices 
to support  such a capability  (as NetSilicon is), it would  be absurd to 
require  support of operations that could never be used.  Now, it is not 
clear  how important  full compliance  to a  PWG spec is, but  if 
compliance requires  supporting a whole set of unusable operations, it 
will become meaningless.
 
I also have  suggested  partitioning this  effort, although not  along the 
same lines. I think we should encourage more discussion on this, 
particularly  on  who plans to apply what  part of  this capability  first 
rather than what appears easier to do first. Indeed, since prototypes  are 
a necessary  part  of the  standard development, I think getting 
volunteers to apply these ideas may be the  determining factor  in the 
"subsetting" definition and order.

Ouch! disallow SETs? 

I agree (propose) with the concept of subsetting. I am thinking more along 
the lines of a "growth path"... where we start with Extranet as target and 
possibly limit our scope to devices, then move to include Intranet and 
also expand to services, then, finally include queues 

But I think SET capability is needed, even at the lowest compliance level. 
If not, how, for example, would a remote manager take a device off-line 
should this be necessary... or post a message to the opPanel?

Harry had brought up  the notion of different classes of compliance in his 
last minutes. I think this  is as it must go. For WBMM monitoring 
applications, any  set  operation let alone queue management must be 
disallowed. But that does not mean that we ought not identify and format 
set operations.

I do think doing some sub-setting makes sense - in the case of queues, not
all devices/services managed by WBMM will have queues to manage. 

Once we understand the potential subsets, we can talk about which ones 
need
to be in WBMM 1.0, and which can follow (or potentially be done in 
parallel.
